Failed to boot android on DragonBoard 845c

Hi team,
I have flashed the latest bootloader for aosp:
96boards/dragonboard845c/linaro/rescue/49/
And flasedh the latest aosp image to the device:
http://snapshots.linaro.org/96boards/dragonboard845c/linaro/aosp-master/340/

But it keeps reporting SufaceFlinger error and won’t boot up.
Full serial log and logcat can be found here.

Do you have a monitor plugged in to it?

Connected the device with a monitor through HDMI, and the monitor seem get no signal all the time.

were you able to solve this issue?

i am running into the same problem here trying to boot my custom build as well as various snapshots, like 366 (current latest), 330, 300 and 278 (which is from 20th April 2020). my setup and custom builds work well on hikey960 and beagleboard x15.

i noticed that the surfaceflinger trace usually does not occur while i prevent the monitor from going into sleep mode. if the display stays awake, the system still does not get displayed but i can see other errors than surfaceflinger in logcat. for example a bunch of processes like apexd get killed due to reasons… i uploaded the first startup trace after flashing 366 snapshot. its available for 30 days: http://ge.tt/1KmW4h53

sometimes a logo is shown right after powering the board, sometimes some frame of the bootanimation. Once i saw the launcher for a very short time (less than a second). But in most cases the display remains black or is complaining periodically about missing signals.

i did not try another display yet. maybe it is some driver thing due to signal processing or something. this will be the next thing to test. i will also test to remove the rb3 kit, to run on a plain dragonboard. dont know if this will make a difference.

finally i solved the issue. all i had to do is to compile the kernel on my own as described by google. seems like the precompiled kernel is broken in some way.

I also compile the kernel on my own, but it does not work.

you mean the issue still occurs? or does compiling the kernel not work?

Just tried to unplug and plug HDMI, finally get to the home screen. It works now.
Thank you bergbiber.

All have to do is build your own android images and flash the images to the device.
1 kernel: use android-mainline
2 android: use aosp master

I hava a one question…

Success to boot Android gki + gsi with HDMI
I want to know that how can I get it to work without HDMI ?

AFAIR, Android requests display to fully boot all the services (surfaceflinger…). So you may want to customize the init flow, or either enabling VFB driver in the kernel (e.g. https://bugs.linaro.org/show_bug.cgi?id=3575#c10) or use dummy HDMI dongle (e.g. https://www.amazon.co.uk/FREEGENE-Displayport-Emulator-Headless-4096x2160/dp/B0747HC25C)

I apply this patch on android gki (5.4) (https://bugs.linaro.org/show_bug.cgi?id=3575#c10)
add CONFIG_FB_VIRTUAL=y
add bootargs: video=vfb:640x480-32@30 vfb.videomemorysize=3145728
But failed to boot android because same reason ( surfaceflinger init fail )
Is there anything I need to boot android without hdmi in kernel 5.4?
Thanks
